MARBLE MOLDI NG AND DISHING MACHINERY COMBINED.

SPECIFICATION forming part of Letters Patent No. 461,094, dated October13, 1891.

Application filed August 11.1891. Serial No.402,375- (No model.)

To on whom, it may concern:

Be it known that I, EDWARD LOGAN CON- KEY, a citizen of the UnitedStates, and a resident of Revere, in the county of Suffolk and State ofMassachusetts, have invented new and useful Improvements in MarbleMolding and Dishing Machinery Combined, of which the following is aspecification.

The objects of my invention are, first, to construct an auxiliarymechanism to be attach ed and secured to an y Work-feeding table bed orframe, such as planer-beds, &c., to dish or mold marble, 330.; second,said attachment to be operated by an independent belt-connection; third,the tool-carriage to have a transverse motion at right angles With thefeed-tawith each other, and, fourth, said carriage to have an automaticstop-motion. These objects I attain by the mechanism illustrated in theaccompanying drawings, in which Figure 1 is a front elevationillustrating the attachment drawn in accordance with my invention. Fig.2 is a vertical detail section on line 2 2, Fig. 1. Fig. 3 is a plandetail section on line 3 3, Fig. 1. Fig. l is a front side elevation.Fig. 5 is a rear side elevation. Fig. 6 is a detail section on line 6 6,Fig. 1, illustrating the two spur-gears that transmit motion to thecarriage worm-shaft.

Similar letters refer to similar throughout the several views.

A denotes the bed or frame, which has guideways A, that thework-carrying table A may be moved by suitable mechanism back and forthin a straight line. This frame or bed A carries two upright frames orstanchions 13, that are secured thereto and braced by the cross-brace B.Said stanchions support a cross-slide C, to which is fitted a carriageD, which carries the rotary tool-shaft d, that has secured thereon thebevel-gear cl, which is actuated by the bevel-gear e, feathered to thecontinuous splined shaft E, which is supported by the arms a D and yokeC. Said shaft E has secured thereon the bevel-gear e, that meshes withthe gear j, feathered to the splined shaft J, which transmits uniformmotion to the tool-shaft (I when the cross-slide C is raised or lowered,to wit: To enable the setting parts of the cutting-tools (1 that areeight in number,

the cross-slide C can be raised, carrying with it the carriage D, yokeC, bevel-gears e,j,j ,j, g, e, and d, spur-gears g and 9 together withthe tool-driving shaft E, shipping-shaft F, levers m and n, rod 11, andsupport 0, which is secured to the cross-slide C, and sustains theshippin g-shaf t F, which has provided thereon friction-nuts f and f oneach side of support 0, to prevent the clutch j from Working out of itsengagement, and which is actuated by the fork is, secured to rod Z, andoperated by the link on and lever n, which carries thecounterbalance-ball o to regulate the friction caused by the nuts f fSaid lever n is secured to the shipping-shaft F, which has securedthereon fingers f and f by which the clutch 9' is drawn out ofengagement, thereby imparting no motion to the carriage D; but whichdoes not interfere with the rotary motion of the tool-shaft (I. Saidfingers or dogs f and f receive their motion from the carriage D as itnears the stanchions B by simply coming in contact with its top, whichthrows the aforesaid fingers f and f to one side, respectively. In caseit is required to traverse only a certain distance the operator cancontrol the aforesaid by use of the shipping-lever f, which has securedthereon a projection 1, that snaps within an opening 2 on projection f,regulating the outward swingof shippinglever f. Said cross-slide C, asbefore stated, can be raised or lowered, to wit: by the haudle h, whichis secured to the shaft H; also, bevel-gears 72, that are in mesh withgears 2 respectively, thereby imparting motion to worm-shafts I, thatenter nuts 0, secured on the cross-slide C. There being more weight atone end of cross-slide C itis necessary to equalize the same, which isaccomplished by the segment 0 and adjustable weight 0 The former has itsfulcrum within the standard 0", which is secured to the top ofstanchions B, and is connected to the yoke C by the chain 0 The carriageworm-shaft G has secured thereon handle G, which can be operated by theworkman when the double -feathered clutch 3' is disengaged from the hubof either gear 7' and 7' which run loose upon shaft J therebytransmitting a reversed motion to carriage worm-shaft G when thefeathered clutch 3' has been shipped to its opposite hub, as representedin Fig. 1, which illustrates the clutch j engaged with the hub of gear jwhich meshes with bevel-gear g,that has the spur-gear g, securedthereto, engaged with spur gear or follower g that is secured uponcarriage worm-shaft G, which imparts the re quired motion to thecarriage D by the wormshaft passing through a nut d secured on the rearside of said carriage D.

Openings 1) are to prevent the operator from raising or lowering thecross-slide 0 too much, which is attained by passing a bolt 3 from thecross-slide through opening I). Said bolt 3 is provided with a nut andwasher 3 to enable the workman to rigidly secure the cross-slide O toany elevation within the limits given by the openings b. The projectionI) is fitted t0 the crossslide O, forming a guideway for same, asillustrated in Fig. 3.

Arm B is secured to the stanchion l3 and floor, which is designed tocarry a loose and fixed pulley B on the shaft of which is secured thebevel-gear b that transmits motion to the driving-shaft J through thebevel: gear j.

Having described my invention, I claim 1. In a dishing-machine, thestanchions B, brace B, shaft H, bevel-gears h and i, worm shafts I,segment 0 adjustable weight 0 standard 0 openings b, projections 1),lifting-handle h, vertical splined driving-shaft J, bevel-gearsj and barm B and fixed and loose driving-pulleys B in combination with thecross-slide 0, provided with bolts 3, guideways I), vertical nuts 0,said cross-slide O havingyoke O and arm 0 secured to same, movablecarriage D, worm-nut d worm-shaft G, tool-shaft d, cutters d bevel-gearsd and e, handles G and f, shipping-shaft F, provided with friction-nutsf and f fingers or dogsf and f lever n, weight 0, link m, rod Z, forkis, feathered double clutch j, loose bevel-gears j and j spur-gear 9,compound with bevel-gear g, spur gear or follower g secured to theaforesaid carriage worm-shaft G, splined shaft E, arm D, bevel-gears eand j, the former secured to shaft E and the other feathered on thevertical splined driving-shaft J, chain 0 arm f, recess 2 011 the same,and projection 1 on handle f, substantially as described, and for thepurpose set forth.
